Improved fan attachment for sewing-machines



UNITED STATES PATENT FFICE.

SAMUEL BURR," OF 4NEW YORK, N. Y., ASSIGNOR TO HIMSELF AND DAVID CONLAN, OF SAME PLACE.

IMPROVED FAN ATTACHMENT F-OR SEWING-MACHINES.

Specification forming part of Let-ters Patent N0. 58,333, dated September 25, 1866.

To all whom it may concern:

Be it known that I, SAMUEL BURR, of New York, of New York county, in the State of New York, have invented a new Fan Mechanism for Sewing-Machines; and I dov hereby declare that the following is a full and exact description thereof, reference being had to the aecompanying drawings, making' part of this specication.

My invention has for its object to provide ameans of Tanning the operative of a sewingmachine (or other machines worked at by 0peratives who apply the motive power) without the employment of any additional motor than is already required to operate the machine and to this end my invention consists in the employment of a fan and suitable mechanism for operating it, where the mechanism for working the fan is connected to and driven by the driving machinery ot' the vmachine itself', as will be hereinafter more fully explained.

To enable those skilled in the art to make and use my invention, I will proceed to more fully describe it, referring by letters to the accompanying drawings, in which- Figure l is an end elevation, and Fig. 2 a front elevation, of an ordinarysewing-machine with my invention embraced therein.

In the several figures the same letter of reference indicates the same part of the machine.

A is the table, B the supports or legs, C the presser-foot, D needle-arm, E workin g mechan ism, and G ba1ance-wheel of a sewing-machine, which may be of any kind, and need not here be specilied in detail.

P is the ordinary driving rock-shaft, on which are secured the treads or foot pieces q q,

`and from which extend, nea-r one end, the

crank or vibrating arm o, from which extends the pitman F, which is connected to the crankpin of the wheel G. t

The parts alluded to thus far form part ofthe sewing-machine, and have no peculiarity of construction and operation.

At each end of the table A is a vertical post or standard, I, and in the upper ends of these posts I is arranged with suitable b-earings, so as to turn freely on its axis, a shaft, m, to which is secured a simple plane of card-board, or any other suitable material, to constitute a fan, L. Near one end of the shaft m projects an arm, k, the extremity ot which is connected by a pitman, h, to the end of arm o, (see Fig. 1,) in such manner that the vibrations of said arm o will be communicated to the arm 7c' and fan L.

It will be seen that as the sewing-machine is run or operated the fan L, through the me dium'of arms o k, pitman 7L, and rock-shaft m, will be rapidly vibrated in the arc of a circle. as indicated by the dotted circle at Fig. 1, and produce acurrent of air over the face and body ot' the operator; and it will be understood that while the cost of applying the fan and its con neeted devices is very little the motive power employed to operate it is almost or quite nominal in quantity, being taken from the driving mechanism of the machine itself.

Of course my invention may be applied with equal facility and advantage to other kinds ot' machines, the gist of my invention being in the idea of a simple fan mechanism connected to and driven bythe driving mechanism ot' the machine.

What I claim as new, and desire to secure by Letters Patent, is-

The employment ot' the vibratory fan L, when arranged with the supporti ngstandards I I and drivingarms lc It, and the treadle of the machine, all as hereinafter specitied.

In testimony whereof I have hereunto set my hand and seal.

J. N MCINTIRE, DAVID OONLAN.
